UNITED PATENT OF Pics.

swAGrNG mooL.

. Application filed June-2,

Be it known that we, JonN S and Romain H. Ro'rHriooK, citizens of the United States, residing at Pittsburg, in the county of Crawford and Statebf Kansas, have invented new and useful Improvements in Swaging Tools, of which the following is a specification.

This invention relates to improvements in swaging tools and has for an object the provision of a tool' of this character by .means of which the ends of pipes may be flared without shutting ofl' flow of water therethrough. e

In the eventof a break in the lead service pipe of a water supply system which ex tends from the street main to a building, an opening must be made in the street to repair the break, while an additional street opening must be made to cut ofl' the water at the main during such repair, as it is impossible to use the ordinary swaglng tool against the pressure of the water.

This objection is overcome in the present invention by providing a tool which has an opening or passage therethrough so that water may pass freely through the tool while the pipe is being flared for the retention of the tail piece and nut of the union and thus permit of the repair of the break without shutting off the water and without making an opening to cut off the water supply from the main.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings V Figure 1 is an elevation of a swaging tool construotedin accordance with the invention. 1

Figure 2 is a sectional view illustrating the position of the tool in use.

Referring to the drawings in detall wherein like characters of reference denote corresponding parts, the reference character 10 indicates the body of the tool which in the present instance is of cylindrical shape and which includes a head 11 and a centering end 12, the latter in the present instance being of a reduced diameter and adapted to fit within the end of a pipe 13. to center the tool. d

The toolfurther includes an annular 1924;. Serial in). 717,430.

flange l l wliich located between the 11 and the centering end 1 2, while a curved flaring face 15 connects thejflange and cert.

telring end,.extend ing from said-flange and er nt e Per h ry; 9f. thei e eri end. This provides means whereby when the centering end 12 is inserted within a pipe as shown in Figure 2 of the drawings, the head 11 may be struck with a hammer or other suitable implement to force the said centering end longitudinally of the pipe was to spread or flare the end of the pipe by contact with the flaring face 15, the purpose being to provide means for retaining the usual tail piece and nutof a union, as is well known in the, art.

The novelty of the present invention resides in the provision of means for relieving the water pressure through the pipe 13 while the latter is being flared so that it will not from the street main. This is accomplished by providing a water passage through the tool. It is preferred to form this passage by providing a longitudinally disposed bore be necessary to cut off the supply of water 16 which extends inwardly from the center- 1 diameter than the bore, so that the pressure of the water at the ]unctureof the bore of the opening 17 is reduced with a consequent reduction of the force of the water at the discharge end of the opening 17. Use of the tool is thus facilitated.

By the use of a tool constructed as described a break in the lead service pipe to a building may be made without cutting off the flow of water through the pipe, one portion of the union which is used to repair the break may be connected to the pipe by the use of the tool just described and may be connected to the other portion of the union, pressure being relieved by opening the curb cock.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such chan es as pended claims.-

Having described the invention what is claimed is.

1. A tool con'lprising a body including a head, a centering extension, an annular flange surrounding the body between said head and extension, 21 flaring i'aee extending from the flange and merging into the center ing extension and a Water outlet passage extending through the body and means included in the passage for reducing the pressure of Water passing therethrough.

2. A tool comprising a body including a head, a centering extension, an annular flange surrounding the body between the head and extension, a flaring face extending from the flange and merging into the centering extension and said body having a longitudinally disposed bore extendii'ig from the outer end of. the centering extension and an opening extending laterally "from said bore and defining a Water passage, said opening being spaced from the inner end of the bore and of larger transverse area than said bore to reduce pressure at the iuneture of the bore and opening and reduce the force of the Water discharge.

In testimony whereof We affix our signatures.
